I installed Camco vent covers over our Fantastic Fans that I upgraded, when I owned a trailer. They seemed to work OK , and were reasonably priced. I have a Fantastic Fan installed on our coach, by the previous owner, and want to install a vent cover on it. I have been reading reviews, and now I am unsure of what brand/model I want to invest in.......so.......I thought, " why not ask the forum" ??? I am leaning towards a Maxxair, but they have different models with prices that go from around $30 to close to $60 !!??? Anyone have a favorite they want to recommend?
I replaced the cover on our bathroom Fantastic fan with a Maxxair II from etrailer.com. The old cover was also a Maxxair, but a different model. As I recall, the installation was easy and the new one has removable clips on one side (not shown in the attached pic) which makes it easy to remove it for cleaning, etc.
